Mammals

American Marten

The American marten, also called pine marten, is a mammal from the Mustelidae family. It is characterized by a long and slender body, a bushy tail, and a triangular head. It can jump from one tree to another.

Pine martens are omnivores, but their diets change seasonally. They are opportunistic hunters and prey on voles, rabbits, or mice.

Black Bear

Black bears are among the many wildlife species to watch out for when hiking through the Beaverhead-Deerlodge National Forest. These omnivorous, medium-sized bears are native to North America. They live in heavily forested areas but sometimes appear in human communities to look for food. 

In fact, the USDA Forest Service proclaimed an ordinance for food storage in human campsites and communities within the Beaverhead-Deerlodge region. The ordinance urged developed campgrounds to have bear-resistant storage containers. The purpose of this restriction is to minimize human and bear conflicts that usually compromise their safety.

Elk

Elk are among the largest deer species in the Cervidae family. Male elks can weigh up to 1,096 lb (497 kg), while females can weigh up to 644 lb (292 kg). The North American elk group consists of several subspecies, such as Roosevelt’s elk, tule elk, and Rocky Mountain elk.

Fisher

Fishers, also called Pekania pennanti, are carnivorous mammals native to North America. Fishers are sometimes called fisher cats because of similarities in size and appearance. However, they are not from the Felidae family. Fishers are closely related to weasels and can be found inhabiting the Beaverhead-Deerlodge National Forest. They are carnivores that primarily prey on hares and porcupines.

Gray Wolf

Wolves, called gray wolves, are large carnivorous canines native to Eurasia and North America. Wolves are social animals that are known to form packs. Their basic social unit consists of a mated pair and their offspring. Packs make hunting easier. However, it is common for lone wolves to wander alone temporarily, especially when trying to form their own pack.

Wolves prey mainly on herbivorous mammals and pursue the old, weak, and sick. They prefer large hoofed mammals like deer, elk, and bison. However, they are not fussy eaters and would settle on consuming small rodents, beavers, and even lizards if there is no better prey.

Lynx

The term lynx refers to any of the four species in the Lynx genus in the cat family. Lynxes are carnivorous mammals that prey on other mammals, such as deer, hares, foxes, and sheep. They inhabit secluded high-altitude forests that are densely covered with tall grasses, trees, and shrubs.

There are four extant species of Lynxes: the Canada lynx, the Iberian lynx, the Eurasian lynx, and the bobcat. Canada lynx and bobcats are the lynx species native to North America.

Northern Water Shrew

The northern water shrew, also called the American water shrew, is a type of nocturnal shrew native to the United States, Canada, and Alaska mountain ranges. American water shrews are the smallest mammalian divers. They can grow about 5.1-6.7 inches long (13 to 17 cm) and weigh about 0.28-0.63 ounces (8 to 18 g).

Northern water shrews hunt insects and other aquatic animals by diving from rocks and other elevated banks.

Wolverine

Wolverines are solitary mammals that dwell in mountainous regions and dense forests. They are the largest terrestrial species of the Mustelidae family. 

Wolverines are predominantly scavengers and would feed on carrion. However, they gained a ferocious reputation because of their power. Wolverines can also hunt and prey on small to medium-sized mammals.
